Postini

Postini was an email security and message-management company founded in 1999, providing hosted spam and virus filtering, email archiving, encryption, and web security for businesses. Google acquired Postini in 2007 (roughly $625M) and folded its capabilities into Google Apps (now Google Workspace); the standalone Postini service was discontinued and customers were transitioned to Google Apps by around 2012. The postini.com domain is now Google-owned and redirects to google.com. This profile is retained as a historical portfolio-lead record; the company has no live, standalone API surface, developer portal, or documentation to enrich.

Postini is profiled on the APIs.io network. Tagged areas include Company, Cybersecurity, Email Security, Spam Filtering, and Message Archiving.
